Question

我已經成功實施幾乎所有類型的過濾器this fiddle：

<div data-ng-app='' data-ng-init="vehicles=[ 
 
        {type:'car',color:'red'}, 
 
        {type:'bike',color:'black'}]"> 
 
    <h1> 
 
     AngularJS <a href='http://www.w3schools.com/angular/angular_filters.asp'> 
 
     Filters Example</a> 
 
    </h1> 
 

 
    <p>Enter text 
 
    <input type='text' data-ng-model='abc' /> 
 
    </p> 
 
    <p>The text you entered is 
 
    <br/> <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_uppercase'>Upper case</a> {{ abc | uppercase }} 
 
    <br/><a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_lowercase'>Lower case</a> {{ abc | lowercase }}</p>Enter amount 
 
    <input type='number' data-ng-model='num1' /> 
 
    <p>The <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_currency'>amount</a> you entered is 
 
    <br/>{{ num1 | currency }}</p> <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_orderby'> Directives Filter example</a> 
 

 
    <br/>Vehicles filtered by type: 
 
    <ul data-ng-repeat="v in vehicles | orderBy:'type'"> 
 
    <li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li> 
 
    </ul> 
 
    <br/>Vehicles <a href='http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_input'>filtered by user input:</a> 
 

 
    <br/> 
 
    <input type="text" ng-model='test' /> 
 
    <ul data-ng-repeat="v in vehicles | filter: 'test' | orderBy:'type'"> 
 
    <li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li> 
 
    </ul> 
 
</div>

一切工作除了input filters。

這是我是如何seeing現在：

爲什麼不打印，並通過用戶輸入過濾陣列？

Answer 1

刪除傳遞給過濾器的單引號'test'。由於它不是一個字符串，它的一個模型，它應該直接傳遞給過濾器。

<ul data-ng-repeat="v in vehicles | filter: test | orderBy:'type'"> 
    <li>{{"Vehicle type is "+v.type +" with color "+ v.color}}</li> 
</ul> 

上述代碼將起作用。
